Anthurium plant named ‘TWYANBD9’

ABSTRACT

A new  Anthurium  plant particularly distinguished by having medium to large, triangular, red-pink, shiny spathes, contrasting, firm/leathery, very shiny, dark metallic leaves that become very dark green as they mature, and a dense, upright, branched, leafy growth habit, is disclosed.

Genus and species: Anthurium hybrida.

Variety denomination: ‘TWYANBD9’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar ofAnthurium, botanically known as Anthurium hybrid, and hereinafterreferred to by the cultivar name ‘TWYANBD9’. The new cultivar originatedfrom a hybridization made in 2003 in Apopka, Fla., USA. The femaleparent was the Anthurium plant, ‘Pink Paradise’ (U.S. Plant Pat. No.11,657), while the male parent was the proprietary Anthurium plant‘H-43’ (unpatented).

The new cultivar was selected in March 2005 from the results of thehybridization and has been asexually reproduced repeatedly by tissueculture in Apopka, Fla., USA over a two and one-half year period. Thepresent invention has been found to retain its distinctivecharacteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Apopka, Fla.

-   -   1) Medium to large, triangular, red-pink, shiny spathes;    -   2) Contrasting, firm/leathery, very shiny, dark metallic leaves        which become very dark green as they mature; and    -   3) Dense, upright, branched, leafy growth habit.

DESCRIPTION OF PHOTOGRAPH

This new Anthurium plant is illustrated by the accompanying photographwhich shows the overall plant habit including blooms, buds and foliageof the plant. The colors shown are as true as can be reasonably obtainedby conventional photographic procedures. The photograph is of a 24-monthold plant grown in a greenhouse in Apopka, Fla.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctivecharacteristics of ‘TWYANBD9’. The data which define thesecharacteristics were collected from asexual reproductions carried out inApopka, Fla. The plant history was taken on 24-month old plants whichwere planted from tissue culture in 25-cm pots and grown in a greenhousewith average daily temperatures of 85° F.-95° F. and average nightlytemperatures of 72° F. to 78° F. Observations were made in March 2007.Color readings were taken under natural light in the greenhouse. Colorreferences are primary to The R.H.S. Colour Chart of The RoyalHorticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘TWYANBD9’ differs from the female parent Anthurium plant ‘PinkParadise’ (U.S. Plant Pat. No. 11,657), by having narrower, shiny,red-pink spathes, while ‘Pink Paradise’ has very large, cordate pinkspathes and lobes flushed with green. ‘TWYANBD9’ has immature leavesthat are very dark with a metallic sheen and become dark-green withmaturity, while ‘Pink Paradise’ has uniformly green leaves. ‘TWYANBD9’has an upright, highly branched growth habit with outward pointingleaves, while ‘Pink Paradise’ has an upright, symmetrical and clumpinggrowth habit that is less dense and has fewer basal branches.

‘TVMANBD9’ differs from the male parent Anthurium plant ‘H-43’(unpatented) by having larger, shiny, red-pink spathes, while ‘H-43’ hassmaller, shiny, very dark-red spathes. ‘TWYANBD9’ has an uprightbranched growth habit with outward pointing leaves, while ‘H-43’ has anupright, rounded growth habit that is less dense with fewer basalbranches and larger leaves. In addition, ‘TYWANBD9’ is more tolerant ofadverse conditions, while ‘H-43’ has spathes and foliage that tend tofade if the plant is exposed to high temperatures.

‘TWYANBD9’ differs from the commercial variety ‘Pippi’ (U.S. Plant Pat.No. 14,475), by having larger spathes that fold upward lengthwise, while‘Pippi’ has smaller, flatter spathes. ‘TWYANBD9’ has shiny, red-pinkspathes that are often tinged with green at the base, while ‘Pippi’ hasuniformly red spathes that are not as shiny. In addition, ‘TWYANBD9’ hasimmature leaves that are very dark with a metallic sheen and becomedark-green with maturity, while ‘Pippi’ has immature leaves that aregreen with darker veins.

‘TWYANBD9’ differs from the co-pending anthurium application ‘TWYANBD18’(U.S patent application Ser. No. 11/906,501) in that ‘TWYANBD9’ haslarger spathes (length is 12.0 cm to 20.0 cm and width is 8.0 cm to 10.0cm) than ‘WYANBD18’ (length is 7.5 cm to 11.5 cm and width is 5. cm to7.5 cm). Additionally, ‘TWYANBD9’ has longer peduncles (45.0 cm to 58.0cm) than ‘TWYANBD18’ (45.0 cm).
